From 3bf8d603fd45649c106cae6290a10f20b1bbb569 Mon Sep 17 00:00:00 2001 From: Martino Papero Date: Wed, 30 Sep 2026 22:10:41 +0200 Subject: Input: atkbd - skip deactivate for Lenovo IdeaPad Slim 3 15IWC11 The internal keyboard on the Lenovo IdeaPad Slim 3 15IWC11 (83RR) does not work correctly with the default i8042 settings. Using i8042.nopnp=1 and i8042.dumbkbd=1 restores keyboard input, but prevents the Caps Lock LED from working. Using i8042.nopnp=1 alone does not fix the keyboard. The laptop works correctly when atkbd_deactivate_fixup is used instead. Add a DMI quirk for the 83RR to enable it. This was tested without any i8042 command-line parameters. Keyboard input and the Caps Lock LED work correctly, including after suspend and resume and after a cold boot.
